Water Quality and Pollution Assessment

Physico-chemical and microbiological characteristics of the water samples were analysed following the standard methods to evaluate the quality of drinking water from (Raw water, Water before treatment, Water after treatment, Tap water) at the Ain Zada Dam to Bordj Bou Arreridj (Algeria) were analyzed. The results revealed that the physico-chemical and hydrochemical characteristics: (Temperature, PH, Conductivity, TDS, Turbidity, Dissolved Oxygen, Dry Residue, Ammonium, Total Hardness, Calcium and Magnesium, Chloride, Bicarbonate, Alkalinity, TAC, Iron, Manganese and Aluminum were found within permissible limits for drinking water as prescribed by WHO especially tap and after treatment water. Pearson correlation analysis, conducted to evaluate the relationship of water quality parameters, revealed a significant positive relationship between Total hardness with each of DO, Nitrate, Chlorides, and temperature (0.979, 0.961, 0.941 and 0.973) and negative significance with most of other parameters. Calcium and Sodium were correlated positively with Sulfate (0.986, 0.602 respectively). The detection of Total coliform, total germ, E. coli, Fecal Streptococciand Clostridium Sulf-Red species was intended for human consumption suggests that Raw water and Water before treatment pose severe health risks to consumers and was found unsuitable for direct human consumption without treatment. The present study recommends mobilization of treatment interventions to protect the households from further possible consequences of using the water.
